An anonymous post on 2ch claims an update on Final Fantasy Versus XIII will arrive via Weekly Jump (presumably in two weeks, on January 21), followed by a Versus XIII presentation on January 22.
Considering the source (anonymous, 2ch, etc.), the rumor’s credibility is weak. Jump usually leaks a week in advance, and there is no flying get (early magazine leaks) for Jump this week as the next issue isn’t scheduled for release until January 21. So if the rumor is true, we would likely find out next Wednesday, January 16.
But while we wait, don’t get excited. (You’re smarter than that.) There are grains of salt to take with this. Lots of them. So take a handful, at least.
A rumor similar to this one popped up in November, which mentioned a presentation between January 15 and 17. I would take it something like this would be held off until E3, especially with Lightning Returns being Square Enix’s main focus right now. But hey, we’re just reporting what we come across.
